as/is Leitz 512738 Polarizing Trinocular Microscope Head Leitz 307-143.004 100W Microscope. (They are described in more detail below.) So that each objective does not need to be continuously recentered, the base of the body tube has the patented Leitz 'objective clutch changer.'īetween the ocular and objective on the body tube there are the following:ġ) Cap analyser support provided with an index line. It serves as a socket for a top analyzer-i.e., a cap nicol prism-to sit in.Ģ) graduated circle with vernier for use with analyzer.ģ) an Amici-Bertrand lens in a centering mount with an iris diaphragm, attached to a slider.Ĥ) Tube analyzer of the anastigmatic type with a Ahrens prism.ĥ) Slot for inserting accessories such as selenite plate, quartz wedge, or compensator. The object stage is circular and rotating. It is graduated around the circumference and has two verniers. The substage illuminating apparatus is what is called the 'two-iris-diaphragm type, model a.' The condenser is made of 5 lenses.

The polarizer is an Ahrens prism mounted in a sleeve at the bottom. A small swing-out lens at the top is attached to a knob. The substage mirror is plano-concave and mounted on a slider attached to a independent swing-out arm. The body tube and substage illuminating illuminating apparatus are linked together by roller-tipped forks that meet a vertical bar. The fork on the body tube is hinged to its collar around the tube and can be swung out of alignment with the bar in order to allow for independent rotation of the analysers in the body and substage.

Readings are taken by means of the body tube and stage graduated circles with verniers. This instrument is accompanied by a standing wooden case for storage. It has a nickel-plated handle and hardware, and angled dovetailing. One ocular (8X) is stored in a sliding tray.Ī smaller box holds objectives and accessories. The box is fitted, made of wood, covered with leather, and lined in red wool. Nickel-plated brackets are attached inside to hold the objectives. At first it appears to be an item sold separately from the microscope, but it has two tracks to slide into the main case. This box includes includes five objectives, each on its own centerable adaptor, and two 'clock-key' wrenches for adjusting the centering. There are two slides for the tube slit: a Glimmer 1/4 wave plate and a Gips Rot I. Also a ground-glass disk a case key one nickel-plated stage clip and an extra small lens for the swing-out arm on the condenser.Extremely rare and hardly known this is a camera and a special device from Leitz Wetzlar (from 1932) MIKAS (part of the MIFILMCA).
